You can, I believe, save the game on the same save file you had been using, so that you don't have to keep making new save games. Though I would recommend having at least two saves that you rotate between, just in case you have an error or your save corrupts.

I downloaded the ultimate fix at 600ko/s, so I thought it was strange...

Well back to the subject! With the mod, my sim could travel to other city's (like apaloosa plains....) very well, but not to other countrys (china, egypt and france). So I strarted by removing the mod, since i have a backup of my family. I tried the game without the mod and everything except traveling worked.

I downloaded the new update and the fix, and installed them. And again, everything worked except traveling...

So I'll wait until seasons came out, I'll install it and see if it work then.

Ooh, there could be a big chance, if you just patched your game to 1.39 TODAY and so on, that the MOD from NRAAS - Twallan was for 1.39 and your game was 1.38, so that could be the reason for the mod not working properly.

Ok so that makes no sense at all. What you can do is look this up on the creators website, perhaps there's an incompatibility issue with another mod or something they aren't aware of after the latest version of the mod.You could ask a question about it there, they are friendly and helpful. Just don't mention having torrented versions of the game. They don't look kindly upon that.
